What is maximum absorbance wavelength?
The absorption is highest at around 510 nm (the wavelength at which absorption reaches its peak is called absorption maximum wavelength).
How do you find the concentration of a solution in Class 9?
The concentration of solution formula is given as follows.
- Cor S = Weight of solute in gramsVolume in litres.
- ppm (A) = Mass of ATotal mass of solution×106.
- Mass percentage of A = Mass of component ATotal mass of solution×100.
- Volume percentage of A = Volume of component ATotal volume of solution×100.
What is saturation level class 9?
A saturated solution is a solution that contains the maximum amount of solute that can be dissolved under the condition at which the solution exists. This state is when the solution has reached a point in which no more solute can be added.
What is a dilute solution Class 9?
Dilute Solution: A solution in which the amount of solute is relatively small compared to the amount of solvent in a given mass of it is called a dilute solution.
What is meant by percentage of solution?
A percentage solution is an amount or volume of chemical or compound per 100 mL of a solution. It is a relative expression of solute to solvent: X amount/100 ml = X% Percentage solutions are a convenient and easy way to record solution concentrations.
What does a 5% solution mean?
5% v / v solution means 5 ml of solute is dissolved 100 ml of solution.
What does a 100% solution mean?
The mass of a solute that is needed in order to make a 1% solution is 1% of the mass of pure water of the desired final volume. Examples of 100% solutions are 1000 grams in 1000 milliliters or 1 gram in 1 milliliter.
What are normal solutions?
A solution made by dissolving 1 g-equivalent weight of a substance in sufficient distilled water to make 1 L of solution.
What is a 1 normal solution?
It is similar to molarity but uses the gram-equivalent weight of a solute in its expression of solute amount in a liter (L) of solution, rather than the gram molecular weight (GMW) expressed in molarity. A 1N solution contains 1 gram-equivalent weight of solute per liter of solution.
How do you create a normal solution?
Normal solutions are prepared by dissolving gram equivalent weight of solute making 1 litre of solution. It means, to prepare 1 liter solution, we have to dissolve the solute equal to the equivalent weight of the solute in grams.
What is standard solution and normal solution?
In analytical chemistry, a standard solution is a solution containing a precisely known concentration of an element or a substance. A known mass of solute is dissolved to make a specific volume. It is prepared using a standard substance, such as a primary standard.
What is standard solution example?
Sodium chloride (NaCl), which is used as a primary standard for silver nitrate (AgNO3) reactions. Zinc powder, which can be used to standardize EDTA (ethylenediaminetetraacetic acid) solutions after it has been dissolved in hydrochloric or sulfuric acid.
What is a standard solution give example?
A standard solution can be prepared by dissolving a primary standard in a suitable solvent (such as distilled water). A primary standard is a soluble solid compound that is very pure, with a consistent formula that does not change on exposure to the atmosphere, and has a relatively high molar mass.
How many types of standard solution are there?
two types
